S13 Sr20det into S14 Chassis. wiring harness, help me out

[ByeByeSti]

so i just bought a redtop sr20det off of Ditch_Bound today for my s14. and now i need to figure out how to wire the harness's.. anyone know of a good write up for this. ive tried searching and all i come up with is shut down links. i know russ prob has a cure to this but who knows. i just spent all my money today basically and have $47 left to my name with no job and no car to drive until my s14 is finished hahaha, therefore im screwed.

also dont say use the search button because i did for the past hour or so, and every link ive found doesnt work. so if anyone could help me out that would be great. also if you dont like thread, dont neg rep. just dont read it then please..

thank you,
pat

[stevejames3]

i dont think spending all but $50 of your money on a swap is very smart, especially without a job.

anyways, wiring is one of those things i wont touch. mainly just harness wiring. i had yuri do mine. im sure you'll be able to find a good write up. did you search Google?

[ByeByeSti]

well i spent it on other parts also but ya. bought a swap, fmic, exedy clutch, b&m short shift kit, koyo rad, nismo motor mounts etc. and a shit ton in gas today. + more but ya.

Installing a S13 SR20DET (red or blacktop) into a 1995 240sx is a very simple task that is not much more

difficult than putting the same motor into a S13 chassis.
There are a few details that make this swap a bit different from swapping into the S13 chassis. The Upper
Engine Harness on the S14 (KA and SR) has the plugs for your:

l

Windshield wiper motor

l

Windshield wiper amplifier

l

ABS sensor for right front wheel

l

ASCD (cruise control).
You will need to rewire all of the accessories that you have on your car to make them work with your
engine and S13 SR20DET harness. If you are unfamiliar with S14's, you will also find the following
differences from the S13

l

Power plugs on the S14 are under the dash (near the ECU)

l

ECU relay is also found under the dash (near the ECU) instead of in the engine compartment as
found on the S13.

l

The water cock valve is located against the firewall (this lets hot coolant into the heater box for
your heater

l

The VSS is a plastic unit (found on the S14 KA and the 97-98 S13 SR20DET Blacktop motors (in
KPH))

l

The S14 KA radiator is thicker than the MT S13 KA/SR radiator with different mounting points

l

Intercooler piping on the S14 is routed differently on the drivers side, although you can still use the
S13 style to route your intercooler piping
Everything bolts up to the S14 chassis. You will need to route one of your heater hoses to the bottom of
the water cock valve so your heater will work properly.

Wiring Information:

*Note: I do not have ABS or CC on my car so I did not wire them up. It should not be difficult to do so
however as you will just need to run a wire from the plug to F3. I will look this up and add it to this
document later on.

Here is a list of things you will need to make your own harness:

l

Electrical Tape (Scotch/3M commercial grade kicks ass)

l

Heat Shrink Tubing of various sizes (buy a couple assorted size packs)

l

1/4" and 1/2" Wire loom (get about 6' of the 1/4" and about 10' of the 1/2")

l

20' of 18 gauge stranded electrical wire

l

20' of 14 gauge stranded electrical wire

l

Solder w/ flux core

l

Soldering Iron

l

Wire Cutters

l

Wire Stripers

l

FSM for your car

l

2 Grounding Ring Terminals

l

Zip Ties
First you will need to locate the plugs needed to make this swap work. Try to get both ends of the power
plugs and of the instrument cluster from the S13 JDM shell to make your harness. If you do not have
these ends, you can either hardwire your harness or you can make your own plugs but you will need to
get male and female ends and rewire both sides (stay away from crimps!). I also highly recommend that
you double check each pin location and confirm that you are wiring it to the correct pin against the FSM
for your car.

(The pin out for this plug is incorrect in my 1995 S14 FSM. I will add a pin out for this soon.)
The basic principle of creating a new intermediary harness is to reconnect your S14 accessories (wiper
motor, wiper amplifier, CC, and ABS) to the main power plug, F3-S14 KA (which plugs into M63-S14 KA

file:///C|/Documents%20and%20Settings/Owner/Deskto...0-%20S13%20SR20DET%20Installation%20Into%20S14.htm (4 of 10)10/15/2004 4:01:47 PM

on the interior side). You will also be wiring the S13 SR power plugs to the F3-S14 KA Power Plug and you
will wire the instrument cluster plug from the F3-S14 KA Power Plug. Once you have made all of the
connections you will be able to plug the F3-S14 KA Power Plug into the M63-S14 KA Power Plug and to
the power plugs of the S13 SR, and you will be able to plug in your accessories and your instrument
cluster.
First, a few words about soldering. If you don't intend to solder all of your connections, stop reading this
right now and figure out the wiring on your own. I do not endorse in any way the use of crimp connectors
for your wiring harness. You will only cause yourself trouble down the road and end up having to redo
things. Make sure you properly strip all wires and properly solder all connections (do not cold solder your
joints or they will fail) and then heat shrink each connection. I then put electrical tape over each heat
shrink connection (I am a bit paranoid) and then loomed the entire thing. The last thing you want to
happen is a failure of a solder joint or something shorting w/ another wire.

Wiper Motor and Wiper Amplifier

F7-S14 KA and F9-S14 KA are both located in the engine bay, against the firewall, on the passenger side.
You will only need to make the F7 to F9 wires long enough to connect to each other (make your wires
about 1.5'). When you make your connections to F3-S14 KA, make sure you have enough room to go
through the firewall and down to the kick panel in the passenger compartment (about 3' should do it).

You will need to ground one wire on F7-S14 KA and one wire on F9-S14 KA to the engine. I used a
generic grounding wire (make sure the wire is the same gauge as the wire you're using) that I grounded
to the intake manifold (where the other two grounding wires are located below the fuel rail).

ECU Relay

This is pretty straight forward. You need to power the ecu relay from F3-S14 KA plug and then run wires
to the power plugs on the S13 SR harness (make the wires from the relay to the ecu about 1' long as the
relay will be left by the ecu and power plug, and make the wires from the relay to the S13 power plugs
about 4-5' long depending on where you put your S13 power plugs in relation to F3-S14 KA).

IACV

The 1995 KA24DE has two IACV's. I hooked the SR20DET IACV up to the IACV Air Regulator power on the
S14. See the S14 FSM for more details. Make this about 4-5' long depending on where you put your S13
power plugs in relation to F3-S14 KA.

O2 Sensor

Since this is a heated O2 sensor, I wired this the same way the rear heated O2 sensor is wired on the
KA24DE (the secondary O2 sensor in the downpipe of the KA). Make this about 4-5' long depending on
where you put your S13 power plugs in relation to F3-S14 KA.

Instrument Cluster

Ideally you will have the other end of the S13 SR20DET instrument cluster plug (this is why it pays to get
front cuts) so you don't have to hardwire this. If you do not have the plug you will need cut the other end
of the harness plug end off of your S13 SR20DET harness and hardwire this (or make your own plug if
you are feeling innovative). The wires do not have to be long as they will go from F3-S14 KA to the
instrument cluster plug near the ECU plug.

Once all connections have been made, double check all of your connections and tape and loom everything
up. You are now ready to plug this into your harness on your motor and into your chassis. Follow the
standard fire up procedures of the engine and make sure that everything works properly. Happy Motoring.

such a good write up, hopefully me and another zilvia member, Will, Ditch_Bound will be able to do my harness on tuesday

[Z U L8R]

@_@!!

Dave =]

[ByeByeSti]

i am not dave, who is this dave you speak of kind sir hahah

[SpdElemts]

Hey do you guys know if its the same for obd2? I'm doing the same for my 1996 s14. Thanks.

[Z U L8R]

there are 2 different layouts for the f3 plug on s14's, some 96's have the same as the 95's and some don't. it's not really based on production date either....i would guess it's determined by what parts nissan had left and where it got assembled lol. double check your f3 wire colors/functioins versus any diagram you EVER use......s14 ecu's are tough to find.
Dave =]

[ByeByeSti]

ohh thank you once again Dave glad you could clear that up

[jt$240]

Is that write up similar for the s13 sr into a s14 (98)? I'm new to the s14 world. I did the wiring for engine into my s13 it was a joke but I've read over the write up posted and seems pretty straight forward. Anyone that has any advice about the wiring into a 98 would be appreciated.

[s14kouki_]

so where will the s14 ka power plug, plug into?

[shift_SRDETuser]

sorry to bump an old a thread -- but is this the same for an s14 series 2 sr20det into an s14? or are the wires different on the series 2 sr20det harness than the s13 sr20det harness?

[jho]

That link is dead, could someone pls hook me up with one?

[Slow Poke]

I am looking for a copy of that PDF file as well! Does anyone have it?

Thanks!!!

yea if anyone has a copy of that pdf can you please upload it somewhere? the archived link is missing pictures

Yea, it's missing a few pictures but basically it's the same thing as the image SLow poke posted. It's actually my picture I made a long time ago based off of sr20.hybrid website. It's not that hard and yo ucan easily identify what plug followed by the wiring colors. The only thing I did to get the car started was connect the positive wire from the starter to the fuse box. With all that, the car should start. Let me know if you need anything else. I just recently redid my sr20det so I still remember what is what.
